Improved elevator-bucket



UNITED STATES PATENT OFFICE.'

HENRY DORER AND JAMES STORMS, OF BUFFALO, NEW YORK.

IMPROVED ELEVATOR-BUCKET.

Specication forming part of Letters Patent No. 56,386, dated July 17,1866.

To all whom it may concern:

Be it known that We, HENRY DORER and JAMES STORMS, of the city ofBuffalo, county of Erie, and State of New York, have invented a new andImproved Elevator-Bucket; and we do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings, making a part of this specification, in Which-Figure I is a transverse section. Fig. [I is a perspective; and Fig. IIIis a top view of the cast malleable iron rim forming the enteringv edgeof the bucket.

The nature of this invention consists in making an elevatonbucket partlyot' tin or sheet-iron and partly ot' cast malleable iron, and connectingthese two parts together in such manner that the cast malleable partshall form a strengthening-rim and entering edge of the bucket, thebucket as a whole being constructed as herein described.

Letters of like name and kindy refer to like parts in each of the gures.4

A represents more particularly the lower or receiving and holding partof the bucket, and is made of tin or sheet-iron in a common and approvedmanner and form. The upper edge of the sheet metal is lapped over andmade double, as shown at a', in order to make it thicker at that part,to receive and hold the cast malleable part B. This rim equals in widthabout one-third the whole depth of the bucket, and is so formed that thesheet-metal part enters within it sufficiently, so that the two partsmay be riveted, bolted, or otherwise fastened together, as shown at o,and the rim i's strengthened by a brace-bar, b, integral therewith. lhisbucket is fastened to the bucket-belt by means of rivets passing throughit and the belt, as shown at d.

In the practical use ot' elevator-buckets it is ascertained that theentering edge is subjected to the greatest wear and strain, and hencevarious methods have been resorted to to render more serviceable thispart of the bucket.

The improvement herein described is considered to be cheaper ot'construction and more durable in use than any other bucket heretoforemade.

The rim B being cast in molds, it can be made very smooth and uniform insize and thickness, and strength may be given it at the corners, whereitis subjected to the greatest wear, and others parts of it may be madelighter, so that the metal may be exactly proportioned, giving strengthand thickness where required and making other parts thin and light wherestrength and thickness are not required; and hence a cheaper and moredurable bucket nlay be made by following this im provement than has everheretofore been used.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

An elevator-bucket constructed as herein described.
